NEED Flex cable

Does anyone know where i can buy a flex cable for a touch dual?
not the keypad flex cable, but an actual flex cable connecting the lcd to the main board... mines got damaged from excessive sliding and now the screen sometimes turns black and other times its fine...
Well, I'm selling my Nike so if you were interested you could take the flex cable from that?
See my sig for details.

Diagnose battery or charge port fail?

I fried my charging port socket (don't ask -- coffee, I think). It smelled burned and the charger tip would get hot in the port. I bought a new charging port panel and properly installed it with the protective film removed from the bottom and carefully connected the ribbon cable. The phone will not accept input through the charging port micro USB, but it will charge on a wireless charger. Could I have fried the connector at the battery through which the plug-in power goes? Is there a separate circuit that inputs current from the wireless charger? Could that explain why changing the charging port circuit panel did not fix the problem? Should I buy a new battery and try that? Diagnostic help would be appreciated.

Qi charging terminals alternative use???

As my microusb jack on my sgs4 is starting to wear out i was wandering if i could use the two terminals on the back for the Qi charging pad for charging with a USB powerblock or computer etc?
What i was thinkin is to take a USB lead and just keep the male USB A plug, bare the wires and then connect the red and black wires to the Qi charging terminals on my phone, thus providing my phone with another means of charging..
So i guess im wondering if its possible to put 5v DC on the Qi pad terminals without damaging anything..
Grateful for any help

Friends the socket was removed and points also ... now the service is bad , i try to solder it but the hole small socket get broken and also the some points get removed , i try to put small metal inside big connector and connect the flex cable to that one and i solder cable from side the connector to the out side of flex cable but the signal is very bad any why to fix it without plug and flex cable as they get damaged ??? like soldering wires between area's ???
So either the motherboard or the USB board lost the antenna connector. Hopefully it's the USB board as you're going to have to replace the board based upon your description.

Can I charge a phone through the testing points ?

Hi folks,
I'm trying to fix my old Nubia with a broken USB port by bypassing the port.
Since it's soldered to the motherboard, it's almost impossible to solder right on the usb pins.
But I've noticed testpoints, and found the VCC one, on which I soldered a wire. another being soldered to the outside of the port for grounding.
I thought I would be able to charge it that way, but it's not showing any signs of life (with or without the battery)
So I have 2 questions:
-can I charge through the testpoints ?
-do I need to send a signal to the ID pin ? (I guess not, I opened up a charge only cable and it had only 2 wires)

I tried charging it with a lab psu and an Aukey Quickcharge 2 charger
Thanks for your help
